PLOW.

SPECIFICATION forming part of Letters Patent No. 234,920, dated November30, 1880.

Application led October 4, 1880. (No model.)

To all whom fit may concern:

Beit known that I, THOMAS MEIKLE, of Louisville, in the county of Jeii'erson and State ot' Kentucky, have invented certain new and usefulImprovementsin Plows; and I do hereby declare the following to be afull, clear, and exact description ot' the invention, such as willenable others skilled inthe art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

This invention relates to an improvement in plows, and it consists in soconstructing the parts that an adjustable shin may be at- .tached to themold-board so as to beheld firmly in place by a single bolt, and at thesame time form part of the landside of the plow.

In the annexed drawings, making a part oi' this specication, Figure l isa side elevation. F g. 2 is a perspective view, showing the plow n iththe shin detached. Fig'. 3 is a vertical section. Fig. 4 is a sectionalbottom view. Fig. 5 is a perspective view ofthe detachable shin-piece.

rIhe same letters are employed in all the iigures in the indication ofidentical parts.

Ais the mold-board. B is the share. Ois the standard. D is thedetachable shin7 and E is the landside.

The mold board A is eut away along its front edge to receive the upperflange of the shin-piece D.

The landside E is cut away in front into the form shown in Figs. l and2, the inner edge being beveled to form the recess shown in Fig. 2,which receives a projection or tongue formed on the lower edge oftheshin-piece, as shown at Dl in Fig. 5. This projection ts closely betweenthe beveled edges ot' the landside and mold-board, while thedownwardlyprojecting flange D2is received into the recess formed at Ebetween the rear end ofthe share and the front end of the landside, inwhich it is contined by the bolt l)3 passing through the ilange into thestandard and frog.

The vertical exposed face ot' the piece D is Hush with the landside, andthe upper inclined face is tlush with the curve ot' the moldboard. Thepiece being attached by a single boltmay be easily detached whenever theedge becomes worn.

I do not claim, broadly, a detachable shinpieee or cutter, my inventionbeing confined to the mode of constructing and attaching it.

What I claim as my invention, and desire to secure by Letters Patent,is-

A plow combining in its construction the mold-board and landside, cutaway to form a recess between their upper edges, and a shin; piecehaving a tongue or projection, which is received between the mold-boardand landside, and a downwardly extending flange, which lies in a recessformed between the landside and share, with which it is i'lush, andconfined by a single bolt, substantially as set forth.

ln testimony that I claim the foregoing I have hereunto set my hand this28th day ot' September, 1880.

THOMAS MEIKLE.
